(6)   The initial principal balance of the Class LTII2B Interest shall equal
     0.05% of the aggregate Cut-off Date Principal Balance of the Group Two
     Mortgage Loans.

(7)   The initial principal balance of the Class LTIIX Interest shall equal the
     excess of (i) 50% of the aggregate Cut-off Date Principal Balance of the
     Mortgage Loans over (ii) the initial principal balance of the Lower Tier
     REMIC II Marker Interests.

(8)   For each Distribution Date, the interest rate for each of the Lower Tier
     REMIC Regular Interests (other than the Class LTII1B, the Class LTII2B and
     the Class LT-IO Interests) shall be a per annum rate (but not less than
     zero) equal to the product of (i) the weighted average of the interest
     rates on the SWAP REMIC Regular Interests for such Distribution Date and
     (ii) a fraction the numerator of which is 30 and the denominator of which
     is the actual number of days in the Accrual Period for the LIBOR
     Certificates, provided however, that for any Distribution Date on which the
     Class LT-IO Interest is entitled to a portion of interest accruals on a
     SWAP REMIC Regular Interest ending with a designation "A" as described in
     footnote 11 below, such weighted average shall be computed by first
     subjecting the rate on such SWAP REMIC Regular Interest to a cap equal to
     Swap LIBOR for such Distribution Date.

(9)   For each Distribution Date, the interest rate for the Class LTII1B Interest
     shall be a per annum rate equal to the product of (i) the weighted average
     of the interest rates on the SWAP REMIC Regular Interests beginning with
     the designation "1" for such Distribution Date and (ii) a fraction the
     numerator of which is 30 and the denominator of which is the actual number
     of days in the Accrual Period for the LIBOR Certificates, provided,
     however, that for any Distribution Date on which the Class LT-IO Interest
     is entitled to a portion of interest accruals on a SWAP REMIC Regular
     Interest ending with a designation "A" as described in footnote 11 below,
     such weighted average shall be computed by first subjecting the rate on
     such SWAP REMIC Regular Interest to a cap equal to Swap LIBOR for such
     Distribution Date.

(10) For each Distribution Date, the interest rate for the Class LTII2B Interest
     shall be a per annum rate equal to the product of (i) the weighted average
     of the interest rates on the SWAP REMIC Regular Interests beginning with
     the designation "2" for such Distribution Date and (ii) a fraction the
     numerator of which is 30 and the denominator of which is the actual number
     of days in the Accrual Period for the LIBOR Certificates, provided,
     however, that for any Distribution Date on which the Class LT-IO Interest
     is entitled to a portion of interest accruals on a SWAP REMIC Regular
     Interest ending with a designation "A" as described in footnote 11 below,
     such weighted average shall be computed by first subjecting the rate on
     such SWAP REMIC Regular Interest to a cap equal to Swap LIBOR for such
     Distribution Date.

(11) The Class LT-IO Interest is an interest-only class that does not have a
     principal balance. For only those Distribution Dates listed in the first
     column of the table below, the Class LT-IO Interest shall be entitled to
     interest accrued on the SWAP REMIC Regular Interest listed in the second
     column below at a per annum rate equal to the excess, if any, of (i) the
     interest rate for such SWAP REMIC Regular Interest for such Distribution
     Date over (ii) Swap LIBOR for such Distribution Date.

     SECTION 2.01. Conveyance of Mortgage Loans

hereby sell, transfer, assign, set over and convey to the Trustee without

of the Trust Fund. Such assignment includes all interest and principal received
on or with respect to the Mortgage Loans on or after the Cut-off Date (other
than Scheduled Payments due on the Mortgage Loans on or before the Cut-off

     It is agreed and understood by the Depositor, the Master Servicer, the
Servicers, the Securities Administrator and the Trustee that it is not intended
that any Mortgage Loan be included in the Trust that is, without limitation,

     In connection with such assignment, the Depositor does hereby deliver to,

documents or instruments with respect to each Mortgage Loan:

          (A) The original Mortgage Note endorsed in blank or, "Pay to the order
     of Citibank, N.A., as trustee, without recourse" together with all riders
     thereto. The Mortgage Note shall include all intervening endorsements
     showing a complete chain of the title from the Transferor to

     appropriate recording office of the jurisdiction in which the Mortgaged
     Property is located and in the case of each MERS Loan, the original
     Mortgage together with all riders thereto, noting the presence of the MIN
     of the Loan and either language indicating that the Mortgage Loan is a MOM
     Loan or if the Mortgage Loan was not a MOM Loan at origination, the
     original Mortgage and the assignment thereof to MERS, with


                                      -60-

<PAGE>

     evidence of recording indicated thereon, or a copy of the Mortgage
     certified by the public recording office in which such Mortgage has been
     recorded.

          (C) In the case of each Mortgage Loan that is not a MERS Loan, the
     original Assignment of each Mortgage in blank or, to "Citibank, N.A., as

     been received from the title insurance company).

          (E) Originals of any intervening assignments of the Mortgage, with
     evidence of recording thereon or, if the original intervening assignment
     has not yet been returned from the recording office, a copy of such
     assignment certified to be a true copy of the original of the assignment
     which has been sent for recording in the appropriate jurisdiction in which
     the Mortgaged Property is located.

          (F) Originals of all assumption and modification agreements, if any.

          (G) If in connection with any Mortgage Loan, the Depositor cannot
     deliver the Mortgage, Assignments of Mortgage or assumption, consolidation
     or modification, as the case may be, with evidence of recording thereon, if
     applicable, concurrently with the execution and delivery of this Agreement
     solely because of a delay caused by the public recording office where such
     Mortgage, Assignments of Mortgage or assumption, consolidation or
     modification, as the case may be, has been delivered for recordation, the
     Depositor shall deliver or cause to be delivered to the Trustee or the
     Custodian on its behalf written notice stating that such Mortgage or
     assumption, consolidation or modification, as the case may be, has been
     delivered to the appropriate public recording office for recordation.
     Thereafter, the Depositor shall deliver or cause to be delivered to the
     Trustee or the Custodian on its behalf such Mortgage, Assignments of
     Mortgage or assumption, consolidation or modification, as the case may be,
     with evidence of recording indicated thereon, if applicable, upon receipt
     thereof from the public recording office. To the extent any required
     endorsement is not contained on a Mortgage Note or an Assignment of
     Mortgage, the Depositor shall make or cause to be made such endorsement.

          (H) With respect to any Mortgage Loan, none of the Depositor, the
     Master Servicer, the Servicers, the Securities Administrator or the Trustee
     shall be obligated to cause to be recorded the Assignment of Mortgage
     referred to in this Section 2.01. In the event an Assignment of Mortgage is
     not recorded, the Servicers, the Master Servicer, the Securities
     Administrator and the Trustee shall have no liability for their failure to
     receive and act on notices related to such Assignment of Mortgage.

     The ownership of each Mortgage Note, the Mortgage and the contents of the
related Mortgage File is vested in the Trustee on behalf of the
Certificateholders. None of the Depositor, the Master Servicer, the Servicers or
the Securities Administrator shall take any action inconsistent with such
ownership and shall not claim any ownership interest therein. The Depositor, the
Master Servicer, the Servicers or the Securities Administrator shall respond to
any third party inquiries with respect to ownership of the Mortgage Loans by
stating that such ownership is held by the Trustee on behalf of the

delivered to the Trustee or the Custodian on its behalf are and shall be held in
trust by the related Servicer, for the benefit of the Trustee as the owner
thereof, and such Servicer's possession of the contents of each Mortgage File so
retained is for the sole purpose of servicing the related Mortgage Loan, and
such retention and possession by such Servicer, is in a custodial capacity only.
The Depositor agrees to take no action inconsistent with


                                      -61-

<PAGE>

the Trustee's ownership of the Mortgage Loans, to promptly indicate to all
inquiring parties that the Mortgage Loans have been sold and to claim no
ownership interest in the Mortgage Loans.

     It is the intention of this Agreement that the conveyance of the
Depositor's right, title and interest in and to the Trust Fund pursuant to this
Agreement shall constitute a purchase and sale and not a loan. If a conveyance
of Mortgage Loans from the Sponsor to the Depositor is characterized as a pledge
and not a sale, then the Depositor shall be deemed to have transferred to the
Trustee all of the Depositor's right, title and interest in, to and under the
obligations of the Sponsor deemed to be secured by said pledge; and it is the
intention of this Agreement that the Depositor shall also be deemed to have
granted to the Trustee a first priority security interest in all of the
Depositor's right, title, and interest in, to and under the obligations of the
Sponsor to the Depositor deemed to be secured by said pledge and that the
Trustee shall be deemed to be an independent custodian for purposes of
perfection of the security interest granted to the Depositor. If the conveyance
of the Mortgage Loans from the Depositor to the Trustee is characterized as a
pledge, it is the intention of this Agreement that this Agreement shall
constitute a security agreement under applicable law, and that the Depositor
shall be deemed to have granted to the Trustee a first priority security
interest in all of the Depositor's right, title and interest in, to and under
the Mortgage Loans, all payments of principal of or interest on such Mortgage
Loans, all other rights relating to and payments made in respect of the Trust
Fund, and all proceeds of any thereof. If the trust created by this Agreement
terminates prior to the satisfaction of the claims of any Person in any
Certificates, the security interest created hereby shall continue in full force
and effect and the Trustee shall be deemed to be the collateral agent for the
benefit of such Person.

     In addition to the conveyance made in the first paragraph of this Section
2.01, the Depositor does hereby convey, assign and set over to the Trustee for
the benefit of the Certificateholders its rights and interests under the Sale
Agreement, including the Depositor's right, title and interest in the
representations and warranties contained in the Sale Agreement, the rights in
the Transfer Agreements described therein, and the benefit of the repurchase
obligations and the obligation of the Sponsor contained in the Sale Agreement to
take, at the request of the Depositor or the Trustee, all action on its part
which is reasonably necessary to ensure the enforceability of a Mortgage Loan.
The Trustee hereby accepts such assignment, and shall be entitled to exercise
all rights of the Depositor under the Sale Agreement as if, for such purpose, it
were the Depositor. The foregoing sale, transfer, assignment, set-over, deposit
and conveyance does not and is not intended to result in creation or assumption
by the Trustee of any obligation of the Depositor, the Sponsor, or any other
Person in connection with the Mortgage Loans or any other agreement or
instrument relating thereto.

     SECTION 2.02. Acceptance by the Trustee of the Mortgage Loans

     Except as set forth in the exception report delivered contemporaneously
herewith (the "Exception Report"), the Trustee acknowledges receipt of the
Mortgage Note for each Mortgage Loan and delivery of a Mortgage File (but does
not acknowledge receipt of all documents required to be included in such
Mortgage File) with respect to each Mortgage Loan and declares that it holds and
will hold such documents and any other documents constituting a part of the
Mortgage Files delivered to it or the Custodian on its behalf in trust for the
use and benefit of all present and future Certificateholders. The Depositor will
cause the Sponsor to repurchase any Mortgage Loan to which a material exception
was taken in the Exception Report unless such exception is cured within 45
Business Days of the Closing Date.

     The Securities Administrator acknowledges receipt of the three Cap
Contracts (forms of which are attached hereto as Exhibits M-1, M-2 and M-3) and
is hereby authorized and instructed to enter into such contracts not in its
individual capacity but solely as Securities administrator on behalf of the
trustee


                                       -62-

for the Supplemental Interest Trust, and is further directed to execute and
deliver the Transfer Agreements and the Sale Agreement.

     The Securities Administrator acknowledges receipt of the Swap Agreement
that will be held in the Supplemental Interest Trust and is hereby instructed to
enter into the Swap Agreement, not in its individual capacity, but solely as
trustee for the Supplemental Interest Trust.

     The Trustee or the Custodian on its behalf agrees, for the benefit of
Certificateholders, and the NIMs Insurer, to review each Mortgage File delivered
to it within 60 days after the Closing Date, to ascertain and to certify, within
70 days of the Closing Date, to the NIMs Insurer, the Depositor the Master
Servicer and the Servicers that all documents required by Section 2.01 (A)-(B),
(C) (if applicable), and (D)-(E), and the documents if actually received by it,
under Section 2.01(F), have been executed and received, and that such documents
relate to the Mortgage Loans identified in Exhibit B-1 that have been conveyed
to it. It is herein acknowledged that, in conducting such review, the Trustee or
Custodian shall not be under any duty or obligation to inspect, review or
examine any such documents, instruments, certificates or other papers to
determine that they are genuine, enforceable or appropriate for the represented
purpose, that they have actually been recorded or that they are other than what
they purport to be on their face. If the Trustee or the Custodian on its behalf
finds any document or documents constituting a part of a Mortgage File to be
missing or defective (that is, mutilated, damaged, defaced or unexecuted) in any
material respect, the Trustee or the Custodian on its behalf shall promptly (and
in any event within no more than five Business Days) after such finding so
notify the NIMs Insurer, the Servicers, the Master Servicer the Sponsor and the
Depositor. In addition, the Trustee or the Custodian on its behalf shall also
notify the NIMs Insurer, the Servicers, the Master Servicer, the Sponsor and the
Depositor if the original Mortgage with evidence of recording thereon with
respect to a Mortgage Loan is not received within 70 days of the Closing Date;
if it has not been received because of a delay caused by the public recording
office where such Mortgage has been delivered for recordation, the Depositor
shall deliver or cause to be delivered to the Trustee or the Custodian on its
behalf written notice stating that such Mortgage has been delivered to the
appropriate public recording office for recordation and thereafter the Depositor
shall deliver or cause to be delivered such Mortgage with evidence of recording
thereon upon receipt thereof from the public recording office. The Trustee or
the Custodian on its behalf shall request that the Sponsor correct or cure such
omission, defect or other irregularity, or substitute a Mortgage Loan pursuant
to the provisions of Section 2.03(c), within 90 days from the date the Sponsor
was notified of such omission or defect and, if the Sponsor does not correct or
cure such omission or defect within such period, that the Sponsor purchase such
Mortgage Loan from the Issuing Entity within 90 days from the date the Trustee
or the Custodian on its behalf notified the Sponsor of such omission, defect or
other irregularity at the Purchase Price of such Mortgage Loan. The Purchase
Price for any Mortgage Loan purchased pursuant to this Section 2.02 shall be
paid to the related Servicer and deposited by the related Servicer in the Master
Servicer Collection Account or related Collection Account, as appropriate,
promptly upon receipt, and upon receipt by the Trustee of written notification
of such deposit signed by a Servicing Officer or receipt of such deposit by the
Trustee or the Custodian on its behalf, upon receipt of a Request for Release
and certification of the related Servicer of such required deposit, shall
promptly release to the Sponsor the related Mortgage File and the Trustee shall
execute and deliver such instruments of transfer or assignment, without
recourse, as shall be requested by the Sponsor and necessary to vest in the
Sponsor or its designee, as the case may be, any Mortgage Loan released pursuant
hereto, and the Trustee shall have no further responsibility with regard to such
Mortgage Loan. It is understood and agreed that the obligation of the Sponsor to
purchase, cure or substitute any Mortgage Loan as to which a material defect in
or omission of a constituent document exists shall constitute the sole remedy
respecting such defect or omission available to the Trustee on behalf of
Certificateholders and the NIMs Insurer. The preceding sentence shall not,
however, limit any remedies available to the Certificateholders, the NIMs
Insurer, the Depositor or the Trustee pursuant to the Sale Agreement, the


                                      -63-

<PAGE>

Transfer Agreements and or the Bring Down Letters. Neither the Trustee nor the
Custodian on its behalf shall be under any duty or obligation to inspect, review
and examine such documents, instruments, certificates or other papers to
determine that they are genuine, enforceable, recordable, duly authorized,
sufficient, legal, valid or appropriate to the represented purpose, or that they
have actually been recorded, or that they are other than what they purport to be
on their face. The Servicers, the Master Servicer, the Securities Administrator
and the Trustee shall keep confidential the name of each Mortgagor except as
required for performance of this Agreement and the Servicers, the Master
Servicer, the Securities Administrator and the Trustee shall not solicit any
such Mortgagor for the purpose of refinancing the related Mortgage Loan;
notwithstanding anything herein to the contrary, the foregoing shall not be
construed to prohibit (i) disclosure of any and all information that is or
becomes publicly known, or information obtained by the Trustee, the Servicers,
the Master Servicer or the Securities Administrator from sources other than the
other parties hereto, (ii) disclosure of any and all information (A) if required
to do so by any applicable law, rule or regulation, (B) to any government agency
or regulatory body having or claiming authority to regulate or oversee any
aspects of the business of the Trustee, the Servicers or that of any Affiliate,
(C) pursuant to any subpoena, civil investigation demand or similar demand or
request of any court, regulatory authority, arbitrator or arbitration to which
the Trustee, the Servicers or any Affiliate or an officer, director, employer or
shareholder thereof is a party or (D) to any Affiliate, independent or internal
auditor, agent, employee or attorney of the Trustee, the Servicers, the Master
Servicer or the Securities Administrator having a need to know the same,
provided that the Trustee, the Servicers, the Master Servicer or the Securities
Administrator, as applicable, advises such recipient of the confidential nature
of the information being disclosed, or (iii) any other disclosure authorized by
the Depositor.

     Within 70 days of the Closing Date, the Trustee (or the Custodian on its
behalf) shall deliver to the NIMs Insurer, the Depositor, the Master Servicer
and each Servicer the Initial Certification, substantially in the form of
Exhibit D attached hereto, evidencing the completeness of the Mortgage Files,
with any exceptions noted thereto.

     SECTION 2.03. Representations, Warranties and Covenants of the Depositor

          (a) The Depositor hereby represents and warrants to the Servicers, the
Master Servicer, the Securities Administrator, the NIMs Insurer and the Trustee
as follows, as of the date hereof:

          (i) The Depositor is duly organized and is validly existing as a
     corporation in good standing under the laws of the State of Delaware and
     has full power and authority (corporate and other) necessary to own or hold
     its properties and to conduct its business as now conducted by it and to
     enter into and perform its obligations under this Agreement and the Sale
     Agreement.

           (ii) The Depositor has the full corporate power and authority to
     execute, deliver and perform, and to enter into and consummate the
     transactions contemplated by, this Agreement and the Sale Agreement and has
     duly authorized, by all necessary corporate action on its part, the
     execution, delivery and performance of this Agreement and the Sale
     Agreement; and this Agreement and the Sale Agreement, assuming the due
     authorization, execution and delivery hereof by the other parties hereto,
     constitutes a legal, valid and binding obligation of the Depositor,
     enforceable against the Depositor in accordance with its terms, subject, as
     to enforceability, to (i) bankruptcy, insolvency, reorganization,
     moratorium and other similar laws affecting creditors' rights generally and
     (ii) general principles of equity, regardless of whether enforcement is
     sought in a proceeding in equity or at law.


                                      -64-
<PAGE>

          (iii) The execution and delivery of this Agreement and the Sale
     Agreement by the Depositor, the consummation of the transactions
     contemplated by this Agreement and the Sale Agreement, and the fulfillment
     of or compliance with the terms hereof are in the ordinary course of
     business of the Depositor and will not (A) result in a material breach of
     any term or provision of the charter or by-laws of the Depositor or (B)
     materially conflict with, result in a violation or acceleration of, or
      result in a material default under, the terms of any other material
     agreement or instrument to which the Depositor is a party or by which it
     may be bound or (C) constitute a material violation of any statute, order
     or regulation applicable to the Depositor of any court, regulatory body,
     administrative agency or governmental body having jurisdiction over the
     Depositor; and the Depositor is not in breach or violation of any material
     indenture or other material agreement or instrument, or in violation of any
     statute, order or regulation of any court, regulatory body, administrative
     agency or governmental body having jurisdiction over it which breach or
     violation may materially impair the Depositor's ability to perform or meet
     any of its obligations under this Agreement.

          (iv) No litigation is pending, or, to the best of the Depositor's
     knowledge, threatened, against the Depositor that would materially and
     adversely affect the execution, delivery or enforceability of this
     Agreement and the Sale Agreement or the ability of the Depositor to perform
     its obligations under this Agreement and the Sale Agreement in accordance
     with the terms hereof.

          (v) No consent, approval, authorization or order of any court or
     governmental agency or body is required for the execution, delivery and
     performance by the Depositor of, or compliance by the Depositor with, this
     Agreement and the Sale Agreement or the consummation of the transactions
     contemplated hereby, or if any such consent, approval, authorization or
     order is required, the Depositor has obtained the same. The Depositor
     hereby represents and warrants to the Trustee with respect to each Mortgage
      Loan as of the Closing Date, and following the transfer of the Mortgage
     Loans to it by the Sponsor, the Depositor had good title to the Mortgage
     Loans and the Mortgage Notes were subject to no offsets, claims, liens,
     mortgage, pledge, charge, security interest, defenses or counterclaims.

          (b) The representations and warranties of each Transferor with respect
to the related Mortgage Loans in the applicable Transfer Agreement, which have
been assigned to the Trustee hereunder, were made as of the date specified in
the applicable Transfer Agreement and brought forward to the Closing Date
pursuant to the related Bring Down Letter. The representations and warranties of
each Transferor with respect to the Mortgage Loans contained in the Bring Down
Letter were made as of the Closing Date. The representations and warranties of
the Sponsor with respect to the Mortgage Loans contained in the Sale Agreement
were made as of the Closing Date. To the extent that any fact, condition or
event with respect to a Mortgage Loan constitutes a breach of (i) both
representation or warranty of the applicable Transferor under the applicable
Transfer Agreements or Bring Down Letters and (ii) a representation or warranty
of the Sponsor under the Sale Agreement, the obligations of the Sponsor under
the Sale Agreement shall be enforced against the Transferor or the Sponsor, as
applicable, as set forth in the Sale Agreement. The Trustee is hereby directed
to and does acknowledge that the Sponsor shall have no obligation or liability
with respect to any breach of a representation or warranty made by it with
respect to any related Mortgage Loans, except as otherwise set forth in the Sale
Agreement, if (as certified to the Trustee by the Sponsor) the fact, condition
or event constituting such breach also constitutes a breach of a representation
or warranty made by the related Transferor in the related Transfer Agreement or
Bring Down Letter, without regard to whether the related Transferor fulfills its
contractual obligations in respect of such representation or warranty. The
Trustee also is hereby directed to and does acknowledge that the Sponsor shall
have no obligation or liability with respect to any breach of a


                                      -65-

<PAGE>

representation or warranty made solely by the Transferors with respect to the
Mortgage Loans, without regard to whether the related Transferor fulfills its
contractual obligations in respect of such representation or warranty. The
Trustee further acknowledges that the Depositor shall have no obligation or
liability with respect to any breach of any representation or warranty with
respect to the Mortgage Loans (except as set forth in Section 2.03(a)(iv)) under
any circumstances.

     In addition to the representations and warranties of the Transferors in the
Transfer Agreements that were brought forward to the Closing Date pursuant to
the related Bring Down Letter, with respect to each Mortgage Loan, each
Transferor made certain additional covenants regarding such Mortgage Loan, as
set forth in the related Transfer Agreement. With respect to any breach of such
additional covenants that materially and adversely affects the interests of the
Certificateholders in such Mortgage Loan, the Sponsor shall (1) use reasonable
efforts to enforce such covenant against the related Transferor and (2) if the
Sponsor successfully enforces any obligation of the related Transferor to
repurchase such Mortgage Loan, the Sponsor shall repurchase such Mortgage Loan
in accordance with this Section 2.03. If the Sponsor does not successfully
enforce the obligation, if any, of the Transferor to repurchase a Mortgage Loan
with respect to any breach of any such additional covenants, the Sponsor shall
have no obligation or right to repurchase or cure such Mortgage Loan.

          (c) Upon discovery by any of the NIMs Insurer, the Master Servicer,
the Securities Administrator, the Depositor, the Servicers or the Trustee of a
breach of any of such representations and warranties that adversely and
materially affects the value of the related Mortgage Loan, Prepayment Charges or
the interests of the Certificateholders, the party discovering such breach shall
give prompt written notice to the other parties. Within 90 days of the discovery
of such breach of any representation or warranty, the applicable Transferor or
the Sponsor, as applicable, shall either (a) cure such breach in all material
respects, (b) repurchase such Mortgage Loan or any property acquired in respect
thereof from the Trustee at the Purchase Price or (c) within the two year period
following the Closing Date, substitute a Replacement Mortgage Loan for the
affected Mortgage Loan. In the event of discovery of a breach of any
representation and warranty of any Transferor or the Sponsor, the Trustee's
rights shall be enforced under applicable Transfer Agreement and the Sale
Agreement for the benefit of Certificateholders and the NIMs Insurer. If a
breach of the representations and warranties set forth in a Transfer Agreement
hereof exists solely due to the unenforceability of a Prepayment Charge, the
Trustee (if it has had actual notice thereof) or the other party having notice
thereof shall notify the related Servicer thereof and not seek to enforce the
repurchase remedy provided for herein unless such Mortgage Loan is not current.
In the event of a breach of the representations and warranties with respect to
the Mortgage Loans set forth in the Transfer Agreement, the Trustee shall use
reasonable efforts to enforce the right of the Issuing Entity to be indemnified
for such breach of representation and warranty. In the event that such breach
relates solely to the unenforceability of a Prepayment Charge, amounts received
in respect of such indemnity up to the amount of such Prepayment Charge shall be
distributed pursuant to Section 4.04(b)(i). As provided in the Sale Agreement,
if the Sponsor substitutes for a Mortgage Loan for which there is a breach of
any representations and warranties in the related Transfer Agreement which
adversely and materially affects the value of such Mortgage Loan and such
substitute mortgage loan is not a Replacement Mortgage Loan, under the terms of
the Sale Agreement, the Sponsor will, in exchange for such substitute Mortgage
Loan, (i) provide the applicable Purchase Price for the affected Mortgage Loan
or (ii) within two years of the Closing Date, substitute such affected Mortgage
Loan with a Replacement Mortgage Loan. Any such substitution shall not be
effected prior to the additional delivery to the Trustee or the Custodian on its
behalf of a Request for Release substantially in the form of Exhibit I and shall
not be effected unless it is within two years of the Startup Day. The Sponsor
indemnifies and holds the Issuing Entity, the Trustee, the Depositor, the
Servicers, the NIMs Insurer, the Master Servicer, the Securities Administrator
and each Certificateholder harmless against any and all taxes, claims, losses,
penalties, fines, forfeitures, reasonable legal fees and related costs,
judgments, and any other costs, fees and expenses that the Issuing Entity, the


                                      -66-

<PAGE>

Trustee, the Depositor, the Servicers, the NIMs Insurer, the Master Servicer,
the Securities Administrator and any Certificateholder may sustain in connection
with any actions of the Sponsor relating to a repurchase of a Mortgage Loan
other than in compliance with the terms of this Section 2.03 and the Sale
Agreement, to the extent that any such action causes (i) any federal or state
tax to be imposed on the Issuing Entity or any REMIC provided for herein,
including without limitation, any federal tax imposed on "prohibited
transactions" under Section 860F(a)(1) of the Code or on "contributions after
the startup day" under Section 860G(d)(1) of the Code, or (ii) any REMIC created
hereunder to fail to qualify as a REMIC at any time that any Certificate is
outstanding. In furtherance of the foregoing, if the Transferor or the Sponsor,
as applicable, is not a member of MERS and repurchases a Mortgage Loan which is
registered on the MERS System, the Transferor or the Sponsor, as applicable, at
its own expense and without any right of reimbursement, shall cause MERS to
execute and deliver an assignment of the Mortgage in recordable form to transfer
the Mortgage from MERS to the Transferor or the Sponsor, as applicable, and
shall cause such Mortgage to be removed from registration on the MERS System in
accordance with MERS' rules and regulations.

     With respect to any Mortgage Loan repurchased by the Sponsor pursuant to
the Sale Agreement, or by any Transferor pursuant to the applicable Transfer
Agreement, the principal portion of the funds received by the related Servicer
in respect of such repurchase of a Mortgage Loan will be considered a Principal
Prepayment and shall be deposited in the related Collection Account pursuant to
Section 3.05. Upon receipt by the Trustee or the Custodian on its behalf, upon
receipt of notice from the related Servicer of receipt by the related Servicer
of the full amount of the Purchase Price for a Deleted Mortgage Loan, and upon
receipt of the Mortgage File for a Replacement Mortgage Loan substituted for a
Deleted Mortgage Loan, shall release and reassign to the Sponsor or the
applicable Transferor, as applicable, the related Mortgage File for the Deleted
Mortgage Loan and shall execute and deliver such instruments of transfer or
assignment, in each case without recourse, representation or warranty, as shall
be necessary to vest in such party or its designee or assignee title to any
Deleted Mortgage Loan released pursuant hereto, free and clear of all security
interests, liens and other encumbrances created by this Agreement, which
instruments shall be prepared by the applicable Transferor, and neither the
Trustee, the Custodian on its behalf nor the Securities Administrator shall have
any further responsibility with respect to the Mortgage File relating to such
Deleted Mortgage Loan.

     With respect to each Replacement Mortgage Loan to be delivered to the
Trustee (or the Custodian on its behalf) pursuant to the terms of this Article
II in exchange for a Deleted Mortgage Loan: (i) the applicable Transferor or the
Sponsor, as applicable, must deliver to the Trustee (or the Custodian on its
behalf) the Mortgage File for the Replacement Mortgage Loan containing the
documents set forth in Section 2.01 along with a written certification
certifying as to the Mortgage Loan satisfying all requirements under the
definition of Replacement Mortgage Loan and the delivery of such Mortgage File
and containing the granting language set forth in Section 2.01; and (ii) the
Depositor will be deemed to have made, with respect to such Replacement Mortgage
Loan, each of the representations and warranties made by it with respect to the
related Deleted Mortgage Loan. The Trustee (or the Custodian on its behalf)
shall review the Mortgage File with respect to each Replacement Mortgage Loan
and certify to the Depositor that all documents required by Section 2.01(A)-(B),
(C) (if applicable), and (D)-(E) have been executed and received.

     For any month in which the Sponsor substitutes one or more Replacement
Mortgage Loans for one or more Deleted Mortgage Loans, the Sponsor will
determine the amount (if any) by which the aggregate principal balance of all
such Replacement Mortgage Loans as of the date of substitution and the aggregate
Prepayment Charges with respect to such Replacement Mortgage Loans is less than
the aggregate Stated Principal Balance (after application of the principal
portion of the Scheduled Payment due in the month of substitution) and aggregate
Prepayment Charges of all such Deleted Mortgage Loans.


                                      -67-

<PAGE>

An amount equal to the aggregate of the deficiencies described in the preceding
sentence (such amount, the "Substitution Adjustment Amount") plus an amount
equal to any unreimbursed costs, penalties and/or damages incurred by the
Issuing Entity in connection with any violation relating to such Deleted
Mortgage Loan of any predatory or abusive lending law shall be remitted by the
Sponsor to the related Servicer for deposit into the related Collection Account
by the Sponsor on the Determination Date for the Distribution Date relating to
the Prepayment Period during which the related Mortgage Loan became required to
be purchased or replaced hereunder.

     Notwithstanding any other provision of this Agreement, the right to
substitute Mortgage Loans pursuant to this Article II shall be subject to the
additional limitations that no substitution of a Replacement Mortgage Loan for a
Deleted Mortgage Loan shall be made unless the Trustee, the Securities
Administrator and the NIMs Insurer shall each have received an Opinion of
Counsel (at the expense of the party seeking to make the substitution) that,
under current law, such substitution will not (A) affect adversely the status of
any REMIC established hereunder as a REMIC, or of the related "regular
interests" as "regular interests" in any such REMIC, or (B) cause any such REMIC
to engage in a "prohibited transaction" or prohibited contribution pursuant to
the REMIC Provisions.

     The Depositor shall amend the Mortgage Loan Schedule to reflect the removal
of such Deleted Mortgage Loan from the terms of this Agreement and the
substitution of the Replacement Mortgage Loan or Replacement Mortgage Loans and
shall deliver a copy of such amended Mortgage Loan Schedule to the NIMs Insurer,
the Servicers, the Master Servicer, the Securities Administrator and the
Trustee. Upon such substitution by the Sponsor, such Replacement Mortgage Loan
or Replacement Mortgage Loans shall constitute part of the Mortgage Pool and
shall be subject in all respects to the terms of this Agreement and the
applicable Sale Agreement, including all applicable representations and
warranties thereof included in the applicable Sale Agreement as of the date of
substitution.

          (d) It is understood and agreed that the representations, warranties
and indemnification (i) set forth in this Section 2.03, (ii) of the Sponsor and
the Depositor set forth in the Sale Agreement and assigned to the Trustee by the
Depositor hereunder and (iii) of each Transferor, assigned by the Sponsor to the
Depositor pursuant to the Sale Agreement and assigned to the Trustee by the
Depositor hereunder shall each survive delivery of the Mortgage Files and the
Assignment of Mortgage of each Mortgage Loan to the Trustee or the Custodian on
its behalf and shall continue throughout the term of this Agreement.

          (e) The Depositor shall deliver a copy of the Mortgage Loan Schedule
to the related Servicer on the Closing Date.

          (f) The Depositor shall notify the Servicers, the Master Servicer, the
Securities Administrator and the Trustee when any NIM Notes are issued and when
such NIM Notes are no longer outstanding.
